# Make into factor:
dyads <- mutate(dyads,
Language_c = factor(Language),
Condition_c = factor(Condition))
# Deviation code with Catalan and Friend as reference level (which is the multiplication by -1)
contrasts(dyads$Language_c) <- (contr.sum(2) * -1) / 2
contrasts(dyads$Condition_c) <- (contr.sum(2) * -1) / 2Fit Bayesian model:

## Samples were drawn using sampling(NUTS). For each parameter, Bulk_ESS
## and Tail_ESS are effective sample size measures, and Rhat is the potential
## scale reduction factor on split chains (at convergence, Rhat = 1).What does the interaction mean? For this the sum-codes need to be checked:
contrasts(dyads$Language_c)## [,1]
## Catalan -0.5
## Korean 0.5contrasts(dyads$Condition_c)## [,1]
## Friend -0.5
## Superior 0.5Get the posterior probability of the interaction and language effects:
posts <- posterior_samples(freq_mdl)Check whether the condition effect is above zero:
sum(posts$b_Condition_c1 > 0) / nrow(posts)## [1] 0.00075Check whether the interaction is above zero:
sum(posts$`b_Language_c1:Condition_c1` > 0) / nrow(posts)## [1] 0.003125Posterior predictive checks to see whether our model could’ve predicted the data.
pp_check(freq_mdl, nsamples = 100)
Looks good.
Analysis: Gesture size
Check frequency of vertical and lateral large gestures… which needs to be divided by the total frequency (since the large gestures are a subset of). If we don’t calculate proportions, then the result would just be rehashing the total frequency result, as we know that overall gesture rates are lower for superior.

dyads <- mutate(dyads,
Character_p = Character / (Character + Observer),
Observer_p = Observer / (Character + Observer),
Viewpoint_diff = Character_p - Observer_p)Do this for speakers to see if this changes for superior versus friend:
viewpoint <- dyads %>% select(Language, ID, Condition, Viewpoint_diff) %>%
pivot_wider(names_from = Condition, values_from = Viewpoint_diff) %>%
mutate(PoliteDiff = Superior - Friend)

Category = ifelse(Category < 0, 'less polite', Category),
